The GLE’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Cayenne doesn’t offer pre-crash pretensioners.

The GLE’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Cayenne doesn’t offer a driver alert monitor.

Both the GLE and the Cayenne have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems and around view monitors.

The GLE’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Cayenne doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLE’s wheelbase is 3.9 inches longer than on the Cayenne (117.9 inches vs. 114 inches).

The GLE’s front to rear weight distribution is more even (53.5% to 46.5%) than the Cayenne’s (56.2% to 43.8%). This gives the GLE more stable handling and braking.

The design of the Mercedes GLE amounts to more than styling. The GLE has an aerodynamic coefficient of drag of .29 Cd. That is significantly lower than the Cayenne (.34 to .35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the GLE get better fuel mileage.

As tested by Car and Driver, the interior of the GLE 450 is quieter than the Cayenne:

The GLE has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Cayenne doesn’t offer a remote starting system.

If the windows are left open on the GLE the driver can close them all from a distance using the remote (remote must be aimed at door sensor). On a hot day the driver can also lower the windows the same way. The driver of the Cayenne can only operate the windows from inside the vehicle, with the ignition on.

The GLE offers an optional 115-volt a/c outlet, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Cayenne doesn’t offer a house-current electrical outlet.
